摘　　要：在分析了机械压力机行程调节的必要性的基础上,分析了偏心套分离式行程调节方式、偏心套嵌套式行程调节方式、牙嵌式有级行程调节方式以及伺服压力机行程调节方式等4种机械压力机行程调节方式的基本工作原理、结构组成、工作特性、适用范围及其优缺点,并对这几种行程调节方式应用于工业实际中的合理性进行了探讨。明确指出交流伺服电动机直接驱动的伺服压力机是实现行程调节的较为理想的方式,值得在工业实际中推广。By analyzing the stroke adjusting necessity of mechanical press, the basic operation principle, the structure composition, the working characteristic, the applicable scope and the strength ＆ weakness of the four stroke adjusting methods of mechanical press have been analyzed, which includes eccentric bushing separated stroke adjusting method, eccentric bushing embedded stroke adjusting method, slipping toothed step stroke adjusting method and servo press＇s stroke adjusting method. The rationality of application in industrial practice about the four stroke adjusting methods has been discussed. It is pointed out that the servo press which is directly driven by AC servo motor is an ideal way to realize stroke adjustment, which is worth promoting in industrial practice.
